[Potentialities of CT with densitometry in the assessment of local diffusion of esophageal cancer]. / Vozmozhnosti KT s densitometriei v utochnenii mestnoi rasprostranennosti raka pishchevoda.

Computer-aided tomographic (CT) examination of 94 patients with esophageal cancer was carried out. Densitometric analysis of computer image of esophageal tumors making use of profile density histograms is presented for the first time. Objective graphic criteria for assessment of the depth of tumor invasion have been developed. CT results were correlated to intraoperative findings and data of histological examination of removed tumors. The sensitivity of the method in assessment of esophageal cancer dissemination was 97.7%, specificity 93.4%.
